I need to make a hole in an old, thick foundation. This drill worked beautifully. Quality of the drill was excellent and I expect to be able to be it multiple times without it wearing out.

4.25" Wet only Core Drill Bit
The absolute best price on the web. Don't waste your money on the expensive Milwaukee, Dewalt, or bosch bits. I get the same amount of drilled holes out of Vevor's bits as I do with the expensive ones. Approx 10-15 perfect cores, throw it away and buy a new one. Works great and gets the job done.

Buy something better
Usually I love their stuff but..... If you can afford to get something better, do it. This thing destroyed itself going through one 8 inch foundation wall in my basement for a two and a half inch hole. The bit literally shredded and the tips ripped out. Wrenched my hand all over the place. Definitely do not recommend.

Does the job, but arrived damaged
Arrived damaged & missing pieces, Vevor did little to help. Poorly packaged & broken open, item was bent and the drill bit needed a $40 adapter to work with Vevor's drill (they don't tell you that & they don't sell the adapter) the only thing Vevor did was offer a small refund, too little & not a solution!

Drilled one hole with it. Well no I didn't even get one hole with it drilled. It started to fold in on its self had water to cool it wasn't drilling to fast hardly any pressure at all. Wouldn't recommend to any one..

Mr
This is a very nice rugged drill but the part of the drill that connects to the drill bits is very unusual. It is larger than almost anything I could find in the way of drill bits. Almost all of the drill bits offered by Vevor are NOT compatible. If you look very closely, there are a couple, but nothing in the size that I wanted. The drill bit that I got is excellent, but it can not be used with this drill. I had to put it on my old hammer drill to get the job done.

Disposable bit
Cored 2 holes. Broke teeth on the last. Swells so you can get all the core out of the bit. Disposable bit.

Great customer service
I have a Vevor 4-in drilling machine and bit great product and I wanted to use this 5-in bit and ordered. It came quickly. I opened it. The product looks very good but unfortunately it was not compatible with my 4-in machine. So please be careful while ordering. This is not compatible with a 4-in machine and you might have to buy a separate drilling machine for this. However, I contacted customer service and they were very great in processing the refund. I haven't used the product but the bit looks pretty solid and it also comes with a free blade.

Well, not really sure how good the bit is, because when I got it out of the box to use it, it only had a 5/8" arbor and won't fit the vevor core drill i bought.

Never used this type of core drill. It was very easy to use,went through 8 inches concrete block dry and with not much effort. Very pleased, I needed this hole drilled for mini split ac and it was perfect for the job.
